DESCRIPTION

2-1/4″ x 4″ Steel Flat Bar CF-1018 is manufactured from AISI 1018 low-carbon steel using the cold finished (CF) process, providing improved dimensional accuracy, smooth surface finish, and consistent mechanical properties. This flat bar features a 2-1/4-inch width, 4-inch thickness, and precise cold-finished dimensions, making it ideal for machining, fabrication, and structural applications where tight tolerances and strength are required.

Applications:
2-1/4″ x 4″ CF-1018 steel flat bar is commonly used in:
• Shafts, supports, and structural components
• Machine parts and tooling fixtures
• Industrial frames and equipment bases
• Fabrication projects requiring precise dimensions
• Automotive, construction, and general engineering applications
• Components requiring welding, drilling, or machining

Advantages:
• Excellent machinability: Ideal for turning, drilling, milling, and finishing
• Smooth surface finish: Cold finished for improved precision and appearance
• Good strength and ductility: Suitable for moderate-load structural applications
• Tight tolerances: More accurate sizing than hot-rolled steel
• Versatile: Can be welded, tapped, drilled, and formed as needed

Summary:
The 2-1/4″ x 4″ CF-1018 steel flat bar is a precision cold-finished product offering reliable strength, dimensional accuracy, and smooth surface finish. It is an excellent choice for structural, machining, and industrial applications requiring consistent performance and versatility.

* Prices are subject to change without notice due to fluctuations in the metals market. | All “Value Length” and “Value Pack” item measurements are subject to standard mill tolerances. | Products may be manufactured several thousandths of an inch over or under the stated dimensions and still be within acceptable mill tolerances. All bar, tube, structural, pipe, sheet, plate, and similar products sold on our website are custom cut to the lengths and sizes selected by the customer at the time of purchase. These are not stocked as pre-cut items. Because each order is cut specifically to customer specifications, all cut materials are considered custom products and are not eligible for cancellation, return, or exchange once production has begun. Our standard cutting tolerances are:

  • Length: +0.125″ / -0.062″
  • During the cutting process, the saw blade removes approximately 1/16″ (kerf) of material. This is a normal part of the manufacturing process and is already included within the stated cutting tolerances.
